Step-by-step solution

To solve the problem, let's determine whether the rate of change between each pair of consecutive points is consistent:

First, calculate the rate of change between the first and second points, (1,3)(5,8)(-1, 3) \rightarrow (5, 8):

ΔYΔX=835(1)=56\frac{\Delta Y}{\Delta X} = \frac{8 - 3}{5 - (-1)} = \frac{5}{6} .

Next, calculate the rate of change between the second and third points, (5,8)(11,13)(5, 8) \rightarrow (11, 13):

ΔYΔX=138115=56\frac{\Delta Y}{\Delta X} = \frac{13 - 8}{11 - 5} = \frac{5}{6} .

Finally, calculate the rate of change between the third and fourth points, (11,13)(17,18)(11, 13) \rightarrow (17, 18):

ΔYΔX=18131711=56\frac{\Delta Y}{\Delta X} = \frac{18 - 13}{17 - 11} = \frac{5}{6} .

All calculated rates of change are 56\frac{5}{6}, indicating a constant rate of change.

Therefore, the rate of change is uniform.
